In recent linguistic theory, there has been an explosion of detailed studies of language variation. This volume applies such recent analyses to the study of child language, developing new approaches to change and variation in child grammars and revealing both early knowledge in several areas of grammar and a period of extended development in others. Topics dealt with include question formation, "subjectless" sentences, object gaps, rules for missing subject interpretation, passive sentences, rules for pronoun interpretation and argument structure. Leading developmental linguists and psycholinguists show how linguistic theory can help define and inform a theory of the dynamics of language development and its biological basis, meeting the growing need for such studies in programs in linguistics, psychology, and cognitive science.

This volume investigates the implications of the study of populations other than educated, middle-class, normal children and languages other than English on a universal theory of language acquisition. Because the authors represent different theoretical orientations, their contributions permit the reader to appreciate the full spectrum of language acquisition research. Emphasis is placed on the principle ways in which data from pathology and from a variety of languages may affect universal statements. The contributors confront some of the major theoretical issues in acquisition.

The recent recognition of sign languages as legitimate human languages has opened up new and unique ways for both theoretical and applied psycholinguistics and language acquisition have begun to demonstrate the universality of language acquisition, comprehension, and production processes across a wide variety of modes of communication. As a result, many language practitioners, teachers, and clinicians have begun to examine the role of sign language in the education of the deaf as well as in language intervention for atypical, language-delayed populations. This collection, edited by Patricia Siple and Susan D. Fischer, brings together theoretically important contributions from both basic research and applied settings. The studies include native sign language acquisition; acquisition and processing of sign language through a single mode under widely varying conditions; acquisition and processing of bimodal (speech and sign) input; and the use of sign language with atypical, autistic, and mentally retarded groups. All the chapters in this collection of state-of-the-art research address one or more issues related to universality of language processes, language plasticity, and the relative contributions of biology and input to language acquisition and use.

A volume on second-language acquisition theory and pedagogy is, at the same time, a mark of progress and a bit of an anomaly. The progress is shown by the fact that the two disciplines have established themselves as areas of study not only distinct from each other, but also different from linguistic theory. This was not always the case, at least not in the United States. The anomaly results from the fact that this book deals with the relationship between L2 theory and pedagogy despite the conclusion that there is currently no widely-accepted theory of SLA. Grouped into five sections, the papers in this volume: * consider questions about L2 theory and pedagogy at the macro-level, from the standpoint of the L2 setting; * consider input in terms of factors which are internal to the learner; * examine the question of external factors affecting the input, such as the issue of whether points of grammar can be explicitly taught; * deal with questions of certain complex, linguistic behaviors and the various external and social variables that influence learners; and * discuss issues surrounding the teaching of pronunciation factors that affect a non-native accent.

Only recently has linguistic research recognized sign languages as legitimate human languages with properties analogous to those cataloged for French or Navajo, for example. There are many different sign languages, which can be analyzed on a variety of levels—phonetics, phonology, morphology, syntax, and semantics—in the same way as spoken languages. Yet the recognition that not all of the principles established for spoken languages hold for sign languages has made sign languages a crucial testing ground for linguistic theory. Edited by Susan Fischer and Patricia Siple, this collection is divided into four sections, reflecting the traditional core areas of phonology, morphology, syntax, and semantics. Although most of the contributions consider American Sign Language (ASL), five treat sign languages unrelated to ASL, offering valuable perspectives on sign universals. Since some of these languages or systems are only recently established, they provide a window onto the evolution and growth of sign languages.

Is children's language acquisition based on innate linguistic structures or built from cognitive and communicative skills? This book summarises the major theoretical debates in all of the core domains of child language acquisition research (phonology, word-learning, inflectional morphology, syntax and binding) and includes a complete introduction to the two major contrasting theoretical approaches: generativist and constructivist. For each debate, the predictions of the competing accounts are closely and even-handedly evaluated against the empirical data. The result is an evidence-based review of the central issues in language acquisition research that will constitute a valuable resource for students, teachers, course-builders and researchers alike.
